Personal Note:
I apologize deeply for not uploading a chapter since two months ago! Chemistry homework has top priority! The chapter may be a bit short, but only I wanted this chapter to really focus on Mukuro, so sorry if you don't like how short it is!

~~~~~~~~~~ Previously on Hidden Eyes ~~~~~~~~~~

"I want to know your past...I really want to know who you are."

"..."

"If you don't want to tell me, then I'll understand-"

"I will tell you."

~~~~~~~~~~ And Now It Continues ~~~~~~~~~~

Mukuro is quiet for a short while and holds Allen close to his chest, having his head rest where his heart is. Allen waits for Mukuro patiently to tell his story, but shortly realizes that- I can't hear Mukuro's heartbeat… Allen looks up to ask when Mukuro finally speaks.

"When I was a child, I was, along with many other innocent children, experimented on by a mafia family. The experiments were so painful to bear through that I thought I was already dead by the time they were done. I will not go through the details of what they did to me...for your sake."

"O-Okay…" Even though Allen is mildly curious as to what the family did to Mukuro, it is probably best that he does not know after seeing Mukuro furrowing his eyebrows, obviously pained by recurring memories.

"At some point...I have had enough...and decided to end the experimenting myself. So, I killed every single member of the family."

Allen's eyes widen at what he just heard. He was only a child...and he managed to just...kill everyone?! Allen shivers, not from fearing Mukuro, but from amazement of how powerful Mukuro can be.

"Tsk. You are shivering quite a bit." Mukuro feels for a blanket nearby and wraps it around the both of them and hugs Allen even closer, as if he needed Allen's warmth to continue through his personal story.

Allen has no complaints and closes his eyes to focus on Mukuro's quiet voice, now realizing that Mukuro does not breathe. " How did you kill them?"

"They experimented on my right eye and I gained hellish abilities from it. It was only fair for me to express my thanks by using those abilities to my full advantage."

"Oh…" Allen glances up at Mukuro, looking closely at the blindfold that conceals the eyes Allen long to stare into. "Is that the reason you cover your eyes?"

"Kufufu...I am wearing this blindfold by force, but I will explain that later. I hope you do not think that my eye makes me so ugly that I need a blindfold for it."

"A-Ah! No, that's not what I meant-"

"Kufufu, I am only teasing you. Do not worry." He strokes Allen's hair for a moment before continuing onto his story. He starts to talk about how he got adopted into another mafia family and took control of one of the members with his abilities in order to kill everyone in the family. Then he took his time to talk about how he was imprisoned in a high-security Italian prison, then later escaping only to enroll in a middle school and take over it completely. Allen listens intently and sometimes has a hard time believing what Mukuro is saying.

I can't believe he did this before he even became an adult...I wonder how powerful he is now.

Hours pass and Allen did not keep track of the time as he was completely absorbed into Mukuro's story. Allen is almost in a daze until Mukuro's tone of voice changes to something colder.

"I never imagined that I would...respect...Tsuna so much since he was a mafia leader. Over time, though, I did...because he was different from all the mafia families I previously knew. Yes, he was naive many times, but he cared for his family. He never treated them as tools, but as a real family. ...Something I never had. I never thought I would like being part of the mafia, but I did...however, that was short-lived."

"What happened?"

"Two of people who were so close to me… Tsuna...died...and Chrome almost died just from trying to protect him. To see Tsuna's lifeless body on the ground and Chrome barely hanging onto her own life while bleeding in my arms…...something within me made me snap."

Mukuro's arms tighten a bit around Allen, but not nearly enough to be painful.

"I took my vengeance and killed the person who took down Tsuna and harmed Chrome. I should have stopped there, but I did not. I went after the family that person was from and killed anyone who tried to stop me. I managed to kill the leader and let the remaining members go. That happened to be a mistake on my part because the surviving members only rebuilt the family to come after me. At that point, I made sure to leave no survivors."

Allen barely holds in his gasp at the image of Mukuro running around, practically a cold-blooded murderer. Logical thoughts tell Allen to step away from the man before anything can happen, but feeling Mukuro's arms around him and the sadness behind Mukuro's voice make him sit still.

"I left the Vongolia family, knowing that everyone in there might be my next victims. They were smart enough not to come after me to tell me to return to the family. Everywhere I ran to, I always feel that spies were after me, whether to kill me for justice or to claim a bounty. Either way, I managed to terminate those spies...but sometimes, the people I've killed may not have been spies, but disgusting, yet...innocent human beings."

"You've killed…"

"...Yes, I have killed innocent civilians in my rage and paranoia. And I only killed more and more until blood of thousands of people coated my hands. At that point, I had no rational thought. Whoever I used to be was gone a long time ago. I was already dead within and assumed that no one else could stop me now. Then...he came."

"You've killed far too many people, many of them being innocent."

"And if you don't move out of the way, you'll be next. Leave me be before I slit your throat."

"I'm not going to let you get away this time. I should have ended you the minute you left the family."

"You think you could stop me?! Kufwahaha! Wishful thinking, but we'll see who'll be left standing!"

"It was a long and brutal battle. Neither one of us wanted to stop fighting. He was always quite stubborn. There was a part of me that wanted him to kill me and end my miserable life. However, my pride would not allow it, as insane as that sounded."

"Your mind is clouded. You're not as good as you used to be."

Mukuro spits out blood as he is on his knees. "Well, this isn't what I expected. I have to say...you surprised me."

"I always anticipated winning against you, but not like this."

"Looks like your wishes came true. Congratulations," Mukuro says with his cold, lifeless smirk.

"I'll live up to my words and end your life here and now."

Mukuro watches as he steps closer to him, ready to give the final blow. "It has been fun….Hibari Kyoya."

"If only I could say the same." Hibari delivers the final blow as he hears Mukuro's head crack from the force of his tonfa. Mukuro's body falls to the ground and there is nothing but cold silence.

Allen is taking his time to absorb everything Mukuro just said. "So you're actually dead…"

"Sort of. I did end up in a rather miserable place called Purgatory where I must repent for my crimes. I have spent centuries sitting in one spot on a cold floor, with my arms chained and my eyes covered, so that I would never cause trouble again…"

"Then...how did you get out?"

"Because of you humans...do not get offended. Your human population is currently getting killed off by both the virus and the Ziva .I was sent here to make sure that you humans make it out of this alive. That does not make me completely free, since I still have a long time to repent."

"That's why you have the chains."

"Yes, exactly."

"So, you're not even a human anymore?"

"No, not really. Does that bother you?" Mukuro slowly loosens his arms around Allen.

"N-NO! It's not like that!" Allen hugs his neck tightly, which surprises Mukuro a fair bit. "I'm just...taken aback by everything that you're telling me. I...just want to thank you, though, for being able to tell me more about you...and I'm sorry for what you had to go through."

"You do not have to apologize. You asked and so I told you about my past. Centuries have passed and everyone I knew is long dead now. I do not have anything left from my past, apart from painful memories. Now...I want to focus on the present." Mukuro tilts Allen's face up towards his. "Do you still bear the same feelings for me or have I changed your mind…?"

"N-No! Of course not!" Allen is shocked that Mukuro would even suggest that.

"Prove to me that your feelings have not changed."

Allen did not take a second to hesitate and pulls his face close to kiss him deeply, letting his feelings be expressed through the kiss. Mukuro presses Allen's body against his to deepen the kiss even further and they stay in that spot until Allen had to part for air.

"A-Ah...is that enough proof?"

"Kufufu...for now, dear Allen~" Mukuro's smirk makes Allen blush pink. "But I am curious about you."

"W-Why?"

"You are the only person here who can see my chains...see me for who I really am. I wonder why you happen to be quite special…"

"I wish I knew the answer to that."

"No matter. I will be sleeping with you tonight."

"W-WHAT?!" Mukuro playfully flicks Allen's forehead. "Ow!"

"Where was your mind at? I still have to resume your punishment. Remember?"

"...Oh, that." Allen rubs his forehead.

"Unless you really want me to sleep with you~ And by that I mean se-"

"Let's just go to bed for the night, okay?!"

"Kufufu, all right, all right."

They both end up sleeping in each other's arms, looking forward to tomorrow when they can finally leave the city and come back to headquarters. Allen never felt safer than being in Mukuro's arms.

Even if you told me that you've done terrible things in the past...I've never changed my feelings about you. Because the you now, is kinder, courageous, and sweet. I want to stand by your side and never let you go. I don't know what'll happen when you finish your job here in my world... I'm scared that you'll leave me once you're done. I can't see my life without you at this point. It's almost as if…...I've fallen in love with you, Mukuro."
